When I was a child I used to be able to prove that 2 + 2 = 5 which, along with other useful skills - like walking on my hands (even standing on them), picking my nose and enjoying eating it, and memorising the lyrics to pop songs in one hearing - I have sadly lost. Anyone remember how it goes?

Anyone got a better, more challenging one to try? I think Alice (of Wonderland and Through The Looking Glass fame) was treated to a few.

ah 1/3 = 0.33 recurring so to disprove your theory.999=11-.999=.0011 * .999=.999when a number is divided by a number equal to that number the number created is always 11/.999 =1.001 recurringtherefore your theory is incorrect

I don't take credit for this, but this is from the original book of Alice in Wonderland:

On about the third page of chapter two, Alice starts speaking out some bizarre equations...

"Let me see: four times five is twelve, and four times six is thirteen, and four times seven is -- oh dear! I shall never get to twenty at that rate!"

Alice is correct. 4*5=12... when expressed in base 18. Bases are different standards by which numbers are measured. We count in base 10, computers count in base 2 (a.k.a. binary). HTML colors are in base 16 (a.k.a. hexadecimal, like 1F(b16) is 31(b10)). So anyway, following this pattern...4*5=12 (b18)4*6=13 (b21)4*7=14 (b24)4*8=15 (b27)4*9=16 (b30)4*10=17 (b33)4*11=18 (b36)4*12=19 (b39)4*13=1A (b42) (or about 32(b10) short of 20). The equation falls apart here. Alice will never get to 20 at this rate. :)

Lewis Carroll wasn't just a writer but also a mathematician, as made evident by such seemingly nonsense equations!

You can see how it hits a problem when it requires a symbol to represent a negative digit (-1).

Just as when incrementing we have to resort to using a symbol that is "above" 9 when we get to the next entry after 19 (so we use A to represent 10, B for 11, and so on - hex buffs will know the drill :)), so when we decrement we have to resort to using a symbol to represent -1 (which implies that the representation for the value that precedes 10 is not 9 or 09, but 1?, where ? represents a negative quantity.
